Table of Contents Generation and Heading ID Assignment for HTML

When working with long HTML documents, providing an easy way to navigate between sections is crucial for a good user experience. One of the most effective ways to achieve this is by adding a Table of Contents (TOC) to your page. However, creating and maintaining a TOC manually can be hard and error-prone. This is where tocify.js comes in—a simple Node.js utility that automatically generates a Table of Contents and assigns unique IDs to headings within the document.

In this blog, we’ll explore how tocify.js can save you time and effort by automating the process of TOC generation and heading ID assignment.

What is tocify.js?

tocify.js is a Node.js utility that processes raw HTML content, identifies all the headings (h1, h2, h3, h4, h5, h6), and generates a Table of Contents (TOC) based on those headings. It also assigns unique IDs to each heading to ensure proper navigation within the document. Whether you’re building a blog, a documentation site, or any long-form content, tocify.js makes adding an interactive TOC to your site a breeze.

  Features of tocify.js

1. Automatic TOC Generation
   The utility automatically creates a TOC based on the headings present in the HTML document. It formats the TOC as a nested unordered list (<ul>) with links pointing to the corresponding headings.
2. Heading ID Assignment
   If your headings do not already have unique IDs, tocify.js automatically assigns them, ensuring proper anchor links for navigation. This is particularly useful if your document doesn't have manually assigned IDs for headings.
3. Supports Multiple Heading Levels
   tocify.js supports all standard HTML heading tags (h1, h2, h3, h4, h5, h6) and creates a nested TOC structure to represent the hierarchy of the headings.
4. Returns Modified HTML
   After processing the HTML, tocify.js returns the modified HTML content with assigned IDs and the generated TOC, ready for integration into your webpage.
